In the crypto world, where volatility is the norm, upcoming decisions by the Bank of Japan (BOJ) are causing considerable concern among investors. The BOJ meets on 18-19 December 2025, and a rate hike to 0.75% is expected, the highest level since 1995. Experts and analysts, including those on the platform X (formerly Twitter), warn that this could trigger significant declines in the bitcoin (BTC) market. Based on historical data and the mechanisms of the global financial system, let’s look at why this decision could bring greater volatility to the cryptocurrency market.
Bitcoin’s Historical Reactions to BOJ Rate Hikes
Analysts, such as those at Coin Bureau, stress that previous interest rate hikes in Japan were always accompanied by sharp drops in the price of bitcoin. Here are the key examples:
- March 2024 (+10 basis points, from -0.1% to 0%): Bitcoin fell by 23%.
- July 2024 (+15 basis points, from 0.1% to 0.25%): A decline of 26.6%.
- January 2025 (+25 basis points, from 0.25% to 0.5%): The biggest crash, down 31.89%.
These figures come from an analysis of bitcoin charts against the US dollar (BTC/USD), where clear correlations between BOJ decisions and price movements are visible. For example, in January 2025, after the hike, bitcoin lost more than 200 billion dollars in market capitalization within a few days. Why does this happen?
Japan is the largest foreign holder of US debt. When the BOJ raises rates, capital flows back to Japan, which reduces dollar liquidity in global markets. Investors who borrowed cheap yen must repay their loans, leading to a sell-off of risky assets such as cryptocurrencies. As @coinbureau noted on X: „When rates rise in Japan, money goes home, dollar liquidity dries up, and assets like BTC get sold.”
Similar warnings come from @Coinvo, who quotes economic experts: „Experts believe that the upcoming rate hike in Japan will drive bitcoin down to 63,000 USD.” This is a level that could mean further correction from current prices (around 85,000 USD as of 15 December 2025).
The Carry Trade Mechanism and the Risk of a Flash Crash
Polish analyst @CryptoStasiak, in his post on X, explains in detail the mechanism that could lead to chaos. For decades Japan kept interest rates low or negative, which made the yen an ideal source of cheap capital. The carry trade is simple: borrow yen at a low interest rate, exchange it for dollars, and invest in assets with higher returns, such as US stocks, bonds or cryptocurrencies.
However, the era of cheap yen is coming to an end. Bloomberg surveyed 50 economists, and all of them expect a hike. As @CryptoStasiak writes: „The entire global financial system will have to reprogram itself.” He recalls „Black Monday” on 5 August 2024, when an unexpected BOJ hike triggered a flash crash: bitcoin fell 16% overnight, and a bloodbath swept through traditional markets.
The key question is: will it be different this time? Unlike previous hikes, this one has been expected for weeks. The market may have already „priced in” the decision, as the current lack of enthusiasm for crypto suggests: bitcoin is behaving like a „shitcoin,” and investor interest is minimal. Nevertheless, the risk remains high. As @CryptoStasiak stresses: „The chances that the decision is already priced in are high, but we shouldn’t feel safe before Thursday.”
What Next for Investors?
For investors, the coming days are a time of heightened vigilance. If history repeats itself, we could see another drop of 20-30%, which would push bitcoin below 70,000 USD. On the other hand, if the market is prepared, the hike could pass without major shocks and even become a catalyst for a rebound.
